Another thing from @leolost , revamping system updates. Trying to trim down AppCenter to only do apps and Settings to handle system administration https://github.com/elementary/switchboard-plug-about/pull/281 https://github.com/elementary/settings-daemon/pull/88
I'm so happy with this. It's so easy and fast and smooth. You can see a list of packages if you really care about that, otherwise it just downloads and prepares the updates and then whenever you decide to restart they get installed. Let me emphasize again how fast it is. Checking for updates is fast, downloading them is fast, installing them is fast. It just works.
